Abstract
Abstract A door hanger device having a horizontal support structure having rollers mounted on the bottom thereof and clamping vise-like structure on the upper surface for clamping and holding at least two doors simultaneously. A vertical support structure is securely fastened to one end of the horizontal support structure and diagonal bracing between the horizontal support structure and the vertical support structure is provided for greatly increasing the overall strength of the device. Door clamping structure similar to the structure mounted on the horizontal support is also provided for the vertical support structure and the vertical clamp devices are adjustable vertically along the vertical support structure. A screw thread being operated with a proper ratio gearing is provided for changing the vertical adjustment of said clamping devices. The horizontal support structure forms a generally U shape so that three doors may be transported and held simultaneously without interfering one with the other. The invention also envisions extension structure for both the horizontal and vertical supports. These extensions will greatly increase the capacity and versatility of the overall device. The extensions also have door clamping vise-like structures mounted thereon and the vertical extension has another screw-threaded adjustable means for varying the vertical position of the associated clamps.

Total Claims: 3
Claim 1
Independent Claim
329 words
A dolly for transporting a plurality of doors and supporting a door while the latter is being hung, said dolly including horizontal and vertical support structures, said horizontal structure including a pair of side-by-side legs having front and rear ends interconnected by a transverse connecting structure extending and rigidly connected between the rear ends of said legs, the lower end of said vertical structure being anchored and braced relative to said connecting structure, said horizontal structure including depending support wheel assemblies supported from the front and rear ends of said legs, said vertical support structure including a pair of vertically spaced apart and aligned forwadly opening clamp structures supported therefrom for adjustable shifting therealong with said clamp structures spaced forwardly of said vertical support structure, said legs being free of transverse connections extending therebetween forwardly of a vertical transverse plane containing said clamp structures, said legs each being provided with longitudinally spaced and aligned upwardly opening front and rear clamp structures for support of a door therefrom in spaced relation relative to a door supported and projecting forwardly from said vertically spaced apart clamp structures in a vertical plane spaced between said legs, adjustment means operative to adjustably position said vertically spaced clamp structures along said vertical support structure, an upstanding extension removably supported from the upper end of said vertical support structure, horizontally forwardly opening clamp means mounted on said upstanding extension for adjustable shifting therealong, and connecting means connecting said clamp means and said vertically spaced clamp structures for simultaneous and equal shifting relative to said vertical extension and said vertical support member, said adjustment means including first screw shaft journalled from said vertical support structure and threadedly engaged with said vertically spaced clamp structures, second screw shaft means journalled from said upstanding extension and threadedly engaged with said forwardly opening clamp means, said second screw shaft member being vertically aligned with and disposed above said first screw shaft member and removably coupled thereto for rotation therewith.

A dolly for transporting a plurality of doors and supporting a door while the latter is being hung, said dolly including horizontal and vertical support structures, said horizontal structure including a pair of side-by-side legs having front and rear ends interconnected by a transverse connecting structure extending and rigidly connected between the rear ends of said legs, the lower end of said vertical structure being anchored and braced relative to said connecting structure, said horizontal structure including depending support wheel assemblies supported from the front and rear ends of said legs, said vertical support structure including a pair of vertically spaced apart and aligned forwadly opening clamp structures supported therefrom for adjustable shifting therealong with said clamp structures spaced forwardly of said vertical support structure, said legs being free of transverse connections extending therebetween forwardly of a vertical transverse plane containing said clamp structures, said legs each being provided with longitudinally spaced and aligned upwardly opening front and rear clamp structures for support of a door therefrom in spaced relation relative to a door supported and projecting forwardly from said vertically spaced apart clamp structures in a vertical plane spaced between said legs, adjustment means operative to adjustably position said vertically spaced clamp structures along said vertical support structure, an upstanding extension removably supported from the upper end of said vertical support structure, horizontally forwardly opening clamp means mounted on said upstanding extension for adjustable shifting therealong, and connecting means connecting said clamp means and said vertically spaced clamp structures for simultaneous and equal shifting relative to said vertical extension and said vertical support member, said adjustment means including first screw shaft journalled from said vertical support structure and threadedly engaged with said vertically spaced clamp structures, second screw shaft means journalled from said upstanding extension and threadedly engaged with said forwardly opening clamp means, said second screw shaft member being vertically aligned with and disposed above said first screw shaft member and removably coupled thereto for rotation therewith.
Claim 3
Dependent Claim
76 words
The combination of claim 1 including an elongated longitudinally forwardly extendable and rearwardly retractable extension carried by each of the forward end of said legs telescopically engaged therewith, and a wheeled tubular extension member support removably telescopically engageable with each of said extensions, when the latter are extended, for support of forward ends thereof, each of said extension member supports including an upwardly opening clamp structure in alignment with the corresponding front and rear clamp structures.
